[url] tags have issues with quoted URLs

[hbtronix]

The plugin seems to cut off titles for quoted URLs and seems generally a bit flaky. To fix, replace the handle() method in link.php with this:

function handle($match, $state, $pos, &$handler) {
    if (preg_match('/^\\[url(=[\'"]?(.+?)[\'"]?)?\\](.+?)\\[\\/url\\]$/', $match, $m)) {
        $url = !empty($m[2])? $m[2] : $m[3];
        $title = $m[3];
    }

    // external link (accepts all protocols)
    if ( preg_match('#^([a-z0-9\-\.+]+?)://#i',$url) ) {
        $handler->_addCall('externallink',array($url,$title),$pos);

    // local link
    } elseif ( preg_match('!^#.+!',$url) ) {
        $handler->_addCall('locallink',array(substr($url,1),$title),$pos);

    // internal link
    } else {
        $handler->_addCall('internallink',array($url,$title),$pos);
    }
    return true;
}
